Rooted in generations of D’Addario string making expertise, Pro-Arte’ Nylon 80/20 Bronze is our archetypal classical set, with a little extra brightness. The bass strings are made with a multifilament nylon core and wound with 80/20 Bronze, to create a shimmering acoustic tone. Coupled with clear nylon treble strings, which deliver sweet, mellow highs, Pro-Arte’ Nylon 80/20 Bronze provides a uniquely bold and bright sound for your classical guitar. This Normal Tension set is our best-selling tension, preferred for the balance of rich tone, comfortable feel, and dynamic projection.
